Comment #6
Section 12VAC5-613-80 – DELETE Items “L” and “M”; both of these items impose unnecessary and inadequate restriction on designers and RMEs to use AOSS in a cost-effective and environmentally sound manner. More over, there is no scientific basis for these rules. AOSS can be design and installed and operated in a responsible manner without these requirements. So, please DELETE both of these items.
